ec3d9dd9c7 Optimizer: add the ObjCBridgingOptimization to optimize ObjectiveC bridging operations. 
Removes redundant ObjectiveC <-> Swift bridging calls.
Basically, if a value is bridged from ObjectiveC to Swift an then back to ObjectiveC again, then just re-use the original ObjectiveC value.

Also in this commit: add an additional DCE pass before ownership elimination. It can cleanup dead code which is left behind by the ObjCBridgingOptimization.

a8ae273a52 [SwiftCompilerSources] Require very recent Swift compiler in HOSTTOOLS mode 
To use new C++ interop features in SwiftCompilerSources, we need a very recent Swift compiler when building with host tools.

This does not affect non-HOSTTOOLS builds.

9f4ce612a2 [SwiftCompilerModules] Link lib_InternalSwiftSyntaxParser to libswift 
To use _RegexParser from SwiftSyntax.

* Create 'libswiftCompilerModules_SwiftSyntax.a' which is a subset of
  'libswiftCompilerModules.a'
* Link 'lib_InternalSwiftSyntaxParser' to
  'libswiftCompilerModules_SwiftSyntax.a'
* Factor out swift runtime linking logic in CMake so that dynamic
  libraries can link to Swift runtime, in addition to executables
* Link 'lib_InternalSwiftSyntaxParser' to swift runtime

2b3980b3e2 [SwiftCompilerSources][build] Require recent Swift compiler in HOSTTOOLS mode 
Some code in SwiftCompilerSources, especially the parts that use C++ interop, triggers bugs in older versions of the Swift compiler. To make sure that `HOSTTOOLS` builds don't produce obscure compiler errors or crashes, let's require a relatively new Swift compiler for `HOSTTOOLS` build.

be711e387f [cxx-interop][SwiftCompilerSources] Fix conversion between std::string and Swift.String 
This fixes a dangling pointer issue when creating a `Swift.String` from `std::string`.

Also fixes a warning:
```
warning: variable 's' was never mutated; consider changing to 'let' constant
    var s = SILBasicBlock_debugDescription(bridged)
    ~~~ ^
    let
```

4011e086f0 Swift optimizer: add Value.makeAvailable and `Value.copy(at:andMakeAvailableIn:) 
Utilities to make a value available to be used in another basic block.
Inserts required `copy_value` and `destroy_value` operations in case the destination block is in a different control region than the value.
For example, if the destination block is in a loop while the value is not in that loop, the value has to be copied for each loop iteration.

cd456fa792 Swift SIL: make Function.name and GlobalVariable.name return a StringRef and not a String 
and introduce the StringRef struct.
It's more efficient.

Also, rename the `HasName` protocol to `HasShortDescription`, which introduces the new requirement `shortDescription`. This is need because `name` now has `StringRef` type and not `String` anymore

537bd07487 [SwiftCompilerModules] Configured Package.swift use its own directory 
Previously, it used ${CMAKE_CURRENT_BINARY_DIR} as the package
directory. However, since that directory contains all build artifacts so
opening it in Xcode shows those unnecessary files.

Intead of using ${CMAKE_CURRENT_BINARY_DIR}, create its own directory in
the root build directory.

d292a95296 [SwiftCompiler/Regex] Use bridged DiagnosticEngine for error reporting 
This fixes:
 * An issue where the diagnostic messages were leaked
 * Diagnose at correct position inside the regex literal

To do this:
 * Introduce 'Parse' SwiftCompiler module that is a bridging layer
   between '_CompilerRegexParser' and C++ libParse
 * Move libswiftParseRegexLiteral and libswiftLexRegexLiteral to 'Parse'

Also this change makes 'SwiftCompilerSources/Package.swift' be configured
by CMake so it can actually be built with 'swift-build'.

eea471fe99 add the ComputeEffects pass 
The ComputeEffects pass derives escape information for function arguments and adds those effects in the function.
This needs a lot of changes in check-lines in the tests, because the effects are printed in SIL

87ae9e3a73 add passes to dump the results of EscapeInfo 
And add test files which uses the passes for verification of EscapeInfo

dc2619f33e Swift Optimizer: add EscapeInfo, a new utility for escape analysis 
It’s a replacement for the old `EscapeAnalysis`, implemented in Swift (instead of C++) and with a much simple design and implementation.
While the old EscapeAnalysis builds a connection graph, the new EscapeInfo just performs a simple def-use and use-def walk in the SIL.
The EscapeInfo does not need to analyze the whole function (like the EscapeAnalysis does), but just the relevant value which is inspected. Therefore EscapeInfo is not an `Analysis` which caches its result across optimization passes - it’s not needed.
